“…Such measurements may identify compounds present in the environment, but do not give insight in the bioavailability of the present toxicants and the joint effects of mixtures of (un)known compounds on biota (Hendriks et al, 1994). Therefore, bioassays are deployed as a complementary tool, giving insight in biological effects.…”

Hence, it is essential to assess the impact of antibiotics on aquatic ecosystems. The aim of the present study was therefore to evaluate the potential of a recently developed test for detecting antibiotics in animal tissue, the Nouws Antibiotic Test (NAT), as a sensitive bioassay to assess the effects of antibiotics in water. To this purpose, we determined the toxicity of sulphamethoxazole, trimethoprim, flumequine, tylosin, streptomycin, and oxytetracycline, using the NAT adapted for water exposure. The sensitivity of the NAT was compared to that of bioassays with bacteria (Microtox), cyanobacteria and green algae. In the Microtox test with Vibrio fischeri as test organism, no effects were observed for any of the test compounds. For three of the six antibiotics tested, the cyanobacteria were more vulnerable than the green algae when using photosynthetic efficiency as an endpoint. The lowest EC50 values for four out of six tested antibiotics were obtained using the NAT bacterial bioassay. The bacterial plate system responded to antibiotics at concentrations in the lg L À1 and lower mg L À1 range and, moreover, each plate proved to be specifically sensitive to the antibiotics group it was designed for. It is concluded that the NAT bioassay adapted for water exposure is a sensitive test to determine the presence of antibiotics in water. The ability of this test to distinguish five major antibiotic groups is a very strong additional value.

BPA is detected in the environment typically at a level of 0.1 ng/mL, 10,11,14 and the regulated environmental standard of NP in Europe is 1 ng/mL. 18 Hence, the sensitivity of the system needs to be improved by an order of magnitude to enable the direct monitoring of these compounds in the environment.…”

A rapid and sensitive analytical method based on column-switching semi-microcolumn high-performance liquid chromatography (HPLC) with electrospray mass spectrometry was developed for determining trace levels of bisphenol A (2,2-bis(4-hydroxyphenyl)propane) and nonylphenol (4-nonylphenol) in river water. An aliquot of sample solution was directly injected into the precolumn packed with Capcellpak MF-Ph for sample cleanup and enrichment. The compounds of interest were then transferred to a C-18 analytical column for main separation through a change in flow path by a programmed switching valve. Bisphenol A, nonylphenol, and interfering substances were satisfactorily separated with a simple gradient elution complete within 35 min. Detection of their deprotonated molecules was conducted in negative ion mode. A reduced flow rate (100 &mgr;L/min) optimized for the narrow bore column was found advantageous in obtaining a high degree of sensitivity during electrospray detection. The influence of carrier additives on sensitivity was also examined. This method produced detection limits of 0.5 ng/mL for bisphenol A and 10 ng/mL for nonylphenol (signal-to-noise ratio 3). Calibration curves were observed in the range of 2.5-50 ng/mL (r(2) = 0.999) for bisphenol A and 50-500 ng/mL (r(2) = 0.998) for nonylphenol. Recoveries of the compounds from spiked distilled water and river water were 99.7-138.5% with a relative standard deviation (RSD) ranging from 2.2-9.7%. Copyright 1999 John Wiley & Sons, Ltd.
